How to set Content-Type for IE in Perl

I am writing a webpage in Perl. I write out the Content Type with this line at the beginning of the script:

print header('Content-Type' => 'text/HTML');

This work in Chrome and Firefox, but in IE, it still try to download the page as a file. What should I do to also make IE work?

You can see the generated headers by running on the command line:

perl -MCGI=:standard -we 'print header( q{Content-Type} => q{text/html} )'

Outputs:

Status: text/html
Content-Type: Content-Type; charset=ISO-8859-1

This is obviously not what you want. There are several ways to pass parameters to the header function. You are calling it like this:

header($content_type, $status);

If you want to call header with named parameters, you have to prefix them with a dash. Anything other than the recognized parameters -type, -status, -expires, and -cookie will be stripped of the initial dash and converted to a header, so both of the following work:

perl -MCGI=:standard -we 'print header( q{-Content-Type} => q{text/html} )'

perl -MCGI=:standard -we 'print header( q{-type} => q{text/html} )'

Outputs:

Content-Type: text/html; charset=ISO-8859-1

However, text/html is the default value for Content-Type, so you don't need to specify the Content-Type at all:

perl -MCGI=:standard -we 'print header()'

Outputs:

Content-Type: text/html; charset=ISO-8859-1

I assume you use CGI.pm. CGI::header does not set a single header, but sets the full HTTP header. From the documentation/examples of header:

      print header('text/plain');

I think you confused CGI::header with a similar named function in PHP. But same name does not mean same functionality.

The CGI documentation shows just -type as the key for Content-Type in header. If it's the only argument, you can omit it and only specify the value.

header( -type => 'text/html' );

# or even

header('text/html');

Fixed by changing the line to:

print "Content-type:text/html\n\n";

Not sure why the original didn't work, but anyways.
